INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

S Rossi A Giovannetti M Corigliano S Di Carlo Universitagrave di Roma ldquoSapienzardquo Dipartimento di Scienze Odontostomatologiche

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

S Rossi A Giovannetti M Corigliano S Di Carlo Universitagrave di Roma ldquoSapienzardquo Dipartimento di Scienze Odontostomatologiche

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

Primary Bone Regeneration (PBR) is a mechanism of natural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics

PBR implants let the patient have quicker prosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implantsitrsquos possible to load them just after 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close incontact with implants and without interposition of connective tissue The aim of this study was to evaluate osseointegration in early loaded PBR implants insertedtogether with bone grafts in atrophic alveolar ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to October 2007 we selected 24 patients (both sexes 42 years mean age wellhealthy no smokers) having maxillary and mandibular partial atrophic alveolar ridges and asking for implant supported prostheses We inserted 78 rot ormer PBRimplants (TMIreg Pressing Dental San Marino Italy) together with a bone graft material (BioOss Geistlich) Minimum implant diameter was 375mm and minimumlength was 105mm The primary implant stability was estimated by RFA When the ISQ resulted ge 57 value in the 2nd stage surgery they were early loaded (15months from surgery) The ISQ values were subsequently estimated every month until the 6th month then at 9 and 12 months The endoral X-rays have beenexecuted to 0 2 6 9 and 12 months

RESULTSIn the 2nd stage surgery a complete bone defect filling was observed in all the cases except one that was characterized by partial bone defect filling (greater than50 and without flap dehiscence) The most significant ISQ values increase was observed in the first 2 months a further ISQ value increasing was observed until the3rd-4th month and successively the ISQ values levelled on constant shares At the end of the second month just 6 implants (77) of 5 different patients didnrsquot show57 ISQ value Among these implants 2 showed clinical mobility (M) in early time (third and fourth month) and they were removed and indicated like failures Theendoral X-ray didnrsquot show any change of the marginal bone level Clinical and X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSThe timing of bone tissue healing around TMI implants overlap timing of a simple fracture of the jaw bones These results showed as early loading of PBR implants

inserted together bone grafts seems to be a valid technique to restore atrophic alveolar ridges shortening healing time and having quicker clinical case resolution

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

S Rossi A Giovannetti M Corigliano S Di Carlo Universitagrave di Roma ldquoSapienzardquo Dipartimento di Scienze Odontostomatologiche

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

INTRODUCTION

The latest and new indications about implant surgery and the constant introduction on the market of new components and methodologies go hand in handwith the ever-increasing demand from our patients for a quicker and quicker functional rehabilitation Primary Bone Regeneration (PBR) is a mechanism ofnatural bone healing leading to consolidation of two bone segments in 6 weeks In Implant-Prosthodontics PBR implants let the patient have quickerprosthetic rehabilitation also in case of severe bone atrophy and after guided bone regeneration In fact with PBR implants itrsquos possible to load them justafter 45 days from implants insertion This depends on primary intention bone healing with direct formation of bone tissue close in contact with implants andwithout interposition of connective tissue The aim of this study was to evaluate early loading of PBR (Primary Bone Regeneration) implants insertedtogether with bone grafts in atrophic maxillary ridges

MATERIALS AND METHODSIn our Prosthodontics Dept Sapienza University of Rome from November 2004 to June 2007 a sinus lifting was performed in 8 patients (56 years mean agemale gender initial bone height of 15 -2 mm and bone width of 5 mm) asking for a fixed implant-supported rehabilitation They signed an informed consentIn every patient 2root former PBR implants (TMIreg Pressing Dental San Marino Italy) having 325 diameter and 105mm length were inserted together witha bone graft material (Physiograftreg Ghimas) 25 months after maxillary sinus augmentation one of the implants was retrieved and processed forundecalcified histology while the other one was loaded The endoral X-rays have been executed to 0 2 6 9 and 12 months

RESULTSFrom the histomorphometric analysis the graft material residuals accounted for the 4698 of the bioptical volume marrow spaces for the 1876 and bonefor the 3287 (new bone 2262 native bone 1025) Well-mineralized regenerated bone with lamellar parallel-fibred structure and Haversian systemssurrounded the residual graft material particles The measured BIC amounted to 1694 No connective tissue was observed at the implant boundary surfaceFrom clinical point of view there was no implant failure at the 2nd stage neither mobility nor bleeding on probing The endoral X-rays showed a completebone defect filling and no change of the marginal bone level was observed Clinical and X-ray results analized with T-Student test were statistically significant

(Plt0005) CONCLUSIONSThese results showed as early loading of PBR implants inserted together with bone grafts appears to be suitable for maxillary sinus floor augmentation alsoin critical condition as minimal vertical bone height and shorter healing time

Objectives The aim of this study was to obtain immediate bone reparation in only 6 wks and to predict primary bone apposition

without intermediate growth of the connective tissue

Methods We inserted 128 PBR (Primary Bone Reparation) implants (TMIreg Pressing Dental RSM) into 42 patients of both

genders aged between 29 and 68 yrs After 45 days 25 implants were removed from their sites carefully chosen so as not

to endanger either the final prosthesis plan or the patients health The removed samples were embedded in resin (Tecnovit

Kulzer) histologically prepared (EXAKT) and stained with hematoxylin eosin and methylene blue The same samples

were then examined histologically under an optical microscope (Zeiss and Leitz) at 50-100-200-400X

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

S Rossi A Giovannetti M Corigliano S Di Carlo Universitagrave di Roma ldquoSapienzardquo Dipartimento di Scienze Odontostomatologiche

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

MATERIALS AND METHODSIn our Prosthodontics Depratment La Sapienza University of Rome from May 2001 to December November 2003 we selected 30 patients (both sexes 49 yearsmean age no smokers) having maxillary total edentulism and asking for fixed prosthetic rehabilitation We inserted 128 root former implants (TMI PressingDental San Marino) they were early loaded after 45 days Minimum diameter was 42mm and minimum length was 13mm Before cementation of each finalrestoration we executed a periapical X-ray using a digital X-ray system (Den Optix Gendex Dentsply Int) The X-ray controls were executed after 1-3-6-9-12months and then yearly

RESULTSMarginal bone levels were evaluated by 2 different operators using a computerised measure system (Vix-win 2000 Gendex Dentsply Int) During the first yearthere was 028mm mean bone loss while during the next two years it was 017mm according to Albrektsson and Zarb implant success criteria (lt1mm during thefirst year and lt02mm during next years) X-ray results analized with T-Student test were statistically significant (Plt0005)

CONCLUSIONSParameters for the valuation of Implantology success have to be established before discussing about obtained results by this experimentation On the basis ofthis osseointegration definition clinical studies have to be purposed to survey the implant stability under functional loading In this order itrsquos necessary thatduring periodic controls implant mobility has to be evaluated and radiographic examinations have to be executed in a reproducible way for determining the stateof perimplant bone tissue health The implant success is evaluated on the following criteria by Albrektsson and Zarb 1) the not splinted implant has to be clinicallyimmovable 2) on the X-ray no perimplant radiotranslucency marks have to be present 3) vertical bone loss has to be lower than 1mm during the first year ofloading and lower than 02mm yearly in the following years 4) each implant has to be without marks or persistent andor not reversible symptoms for examplepain infections neuropathies paresthesis or penetration into the mandibular canal 5)prosthetic restoration has to satisfy function and aesthetics On thesepreliminary remarks in the anterior upper and lower sectors it should occur a success rate of 90 and 85 on long time respectively after 5 and 10 years in theposterior sectors these percentages have to be about 85 after 5 years and 80 after 10 years The obtained results from this experimentation are encouragingfully respecting implant success criteria by Albrektsson and Zarb These results showed as early loaded implants supporting overdenture are clinically andradiographically well osseointegrated

Uso degli impianti TMI nella Riparazione Ossea Primaria nei post-estrattivi a carico immediato

S Rossi A Giovannetti M Corigliano S Di Carlo Universitagrave di Roma ldquoSapienzardquo Dipartimento di Scienze Odontostomatologiche

Insegnamento di Protesi Dentaria I Titolare Prof S Di Carlo

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

connettivale di mineralizzazione della trama connettivale cosigrave come previsto dai protocolli per lrsquoottenimento dellrsquoosteointegrazione Lrsquoosteointegrazione necessita di 90

giorni di tempo per lrsquoapplicazione di un carico funzionale corretto infatti i tessuti traumatizzati riparano e si organizzano per seconda intenzione con una sequenza di

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

caratterizzato da un aspetto radiciforme sviluppato sul principio dellrsquoaccoppiamento conico tra impianto ed un sito ricevente di identica forma e dimensioni con un collo

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso

Introduction ndash It has been clearly proved by Ludwig through Fourierrsquos analysis [ Ludwig1993] that ultraweak signals are easly recognazed compared with the background noise if they present a patternthe signals the living matter is able to recognized among a variety of interferential signals are highly complex that is they are made up of different frequency bands Infact the complex signal reaches the biological system as a repetition of weak signals but connected among them in a fixed pattern and it is the

repetition of this pattern that distinguish the ldquotrue signalrdquo from the background noise The action of the CMF identifies as the sum of the effects of superimposed continous and pulsed magnetic fields on biological systemsOn the bone tissue is possible to obtain a neo-osteomorphogenesis increasing the gene expression of the morphogenetic proteins

and modulating the osteoclastogenetic proteins action The same results we can obtain on soft tissue The target of our clinical trial ldquoin vivordquo can demonstrate the effects of Combined Magnetic Field on the bone tissue in oral implantology

Methods 458 patients of both genders aged between 35 and 72 yrs underwent implant surgery associated with GBR according to the protocol of the PBR implant system 1024

fixtures were inserted by means of the TMIreg implant system (Pressing Dental RSM) The MET and CMF (MFI Italy) were applied to all patients for 74 days

Osteogenesis was radiologically controlled after 30 60 90 and 120 days All implants were loaded in 120 days

INTRODUZIONE

La terapia implanto-protesica ha rappresentato negli ultimi decenni uno dei maggiori progressi ottenuti in ambito odontostomatologico Lrsquoavvento dellrsquoosteointegrazione ha radicalmente modificato lrsquoapproccio alla terapia implantare portando allo sviluppo di protocolli chirurgici e protesici standardizzati La riduzione o lrsquoeliminazione dellrsquointervallo di tempo tra lrsquoinserimento della fixture e la sua protesizzazione ha rappresentato quindi uno dei principali temi di ricerca in campo implantologico

MATERIALI E METODI

Lo scopo di questo lavoro egrave dimostrare i vantaggi offerti dalla Riparazione Ossea Primaria (ROP) nellrsquoapplicazione di uno o piugrave elementi a supporto implantare con carico immediato secondo un meccanismo di guarigione ossea naturale per prima intenzione Per carico immediato si intende lrsquoapplicazione di carichi (o forze) agli impianti subito dopo il loro posizionamento

Diversi autori hanno parlato perograve di carico immediato anche quando lrsquoapplicazione di forze non egrave immediata ma avviene dopo 24 ore 72 ore o anche a distanza di una

settimana Tale protocollo egrave in grado di offrire il vantaggio di ridurre le procedure chirurgiche e i tempi di attesa per la riabilitazione protesica provvisoria senza la

necessitagrave di dover ricorrere a protesi rimovibili Grazie allrsquoapplicazione del restauro provvisorio lrsquoosso risulta uniformemente ma non eccessivamente caricato ed egrave noto

come il carico occlusale induca una microstimolazione capace di incrementare qualitativamente e quantitativamente il processo di osteogenesi La ROP egrave un

meccanismo di guarigione ossea per prima intenzione mediante il quale due segmenti ossei traumatizzati con frattura semplice si consolidano in un periodo fisiologico

di sei settimane per rimodellamento Haversiano e lrsquoapplicazione di osso primario direttamente sullrsquoimpianto senza passare attraverso le fasi osteoclastica-macrofagica

sette fasi Lrsquoosteoconnesione egrave un processo di riparazione ossea per prima intenzione che si svolge in tre passaggi ed in 42 giorni Lrsquoimpianto a ROP TMIreg egrave

cilindrico e liscio di 25 mm di altezza ed un corpo a conicitagrave progressiva dotato di spire automaschianti a passo fisso Il corpo implantare egrave attraversato da 6 canali

verticali i quali evitano la compressione dei liquidi biologici depositati allrsquointerno della cavitagrave consentendone il deflusso

RISULTATI

Il termine di ROP risulta del tutto giustificato in implantoprotesi odontoiatrica percheacute la riparazione ossea che avviene intorno agli impianti TMIreg presenta gli stessi quadri istologici con un netto miglioramento dei tempi di guarigione Garantisce lrsquoattivazione delle cellule ossee quiescenti non egrave preceduta da riassorbimento neacute da formazione di tessuto cartilagineo o connettivo egrave quindi ldquodirettardquo

CONCLUSIONI

Questa ricerca egrave iniziata nel gennaio 2006 sono stati inseriti 82 impianti 51 nel mascellare superiore e 31 nella mandibola con lunghezze comprese tra 13 e 15 mm e Oslash tra 37 a 47 mm Al termine di questa prima fase di sperimentazione tutti gli impianti hanno raggiunto una valida osteoconnessione risultando una percentuale di successo del 100 Va tuttavia sottolineato che ancora tutti gli impianti non sono stati finalizzati protesicamente Possiamo affermare che gli impianti a ROP TMIreg consentono di accorciare notevolmente i tempi di guarigione garantendo una piugrave rapida risoluzione del caso
